Consider the following routing table at an IP router: Network No. Net Mask Next Hop 128.96.170.0 255.255.254.0 Interface 0 128.96.168.0 255.255.254.0 Interface 1 128.96.166.0 255.255.254.0 R2 128.96.164.0 255.255.252.0 R3 0.0.0.0 Default R4 For each IP address in Group I identify the correct choice of the next hop from Group II using the entries from the routing table above. Group I Group II i) 128.96.171.92 a) Interface 0 ii) 128.96.167.151 b) Interface 1 iii) 128.96.163.151 c) R2 iv) 128.96.165.121 d) R3 e) R4

Correct Answer is : i – a, ii – c, iii – e, iv – d

i – a, ii – c, iii – e, iv – d

i – a, ii – d, iii – b, iv – e

i – b, ii – c, iii – d, iv – e

Consider the following routing table at an IP router:

Network No.	Net Mask	Next Hop
128.96.170.0	255.255.254.0	Interface 0
128.96.168.0	255.255.254.0	Interface 1
128.96.166.0	255.255.254.0	R2
128.96.164.0	255.255.252.0	R3
0.0.0.0	Default	R4

For each IP address in Group I identify the correct choice of the next hop from Group II using the entries from the routing table above.
Group I Group II
i) 128.96.171.92 a) Interface 0
ii) 128.96.167.151 b) Interface 1
iii) 128.96.163.151 c) R2
iv) 128.96.165.121 d) R3
e) R4

i – a, ii – c, iii – e, iv – d
i – a, ii – d, iii – b, iv – e
i – b, ii – c, iii – d, iv – e
i – b, ii – c, iii – e, iv – d
